If an angular momentum of a body of fixed M.I. increases by

50 \%

, its kinetic energy of rotation increases by:

View answer and explanation

Correct option: D

125 \%

Option D (

125 \%

) is correct because the kinetic energy of rotation is proportional to the square of the angular momentum, so a 50% increase in angular momentum results in a 125% increase in kinetic energy.
